Configuring Interoperation Between CE Series Switches and Servers Using Intel(R) Server Adapter I340 Network Adapters (IEEE 802.3ad Mode)

Configuring Interoperation Between CE Series Switches and Servers Using Intel(R) Server Adapter I340 Network Adapters (IEEE 802.3ad Mode)

Applicable Products and Versions

This example applies to CE series switches of V100R001C00SPC200 or later versions.

Networking Requirements

As shown in Figure 3-2, a server uses a network adapter group consisting of two Intel(R) Server Adapter I340 network adapters that connect to different interfaces of SwitchA. It is required that link aggregation be configured on links between the CE series switch and server to improve the interface bandwidth and the links load balance service traffic.

Figure 3-2 Interoperability between a CE series switch and a server

Configuration Roadmap

The network adapter group in load balancing mode can meet the preceding requirement. The configuration roadmap is as follows:
  1. Create an Eth-Trunk on the CE series switch and configure the Eth-Trunk to work in static LACP mode to improve the interface bandwidth and reliability.
  2. Configure the network adapter group to work in dynamic link aggregation (IEEE 802.3ad) mode to improve the link reliability and interface bandwidth and implement link load balancing.
NOTE:

The load balancing mode applies to scenarios in which a server connects to a switch or a stack system.

Procedure

  1. Configure an Eth-Trunk and a VLAN on the CE series switch.

    <HUAWEI> system-view

    [*HUAWEI] commit                                                              
    [~SwitchA] vlan batch 2                             //Create VLAN 2.                 
    [*SwitchA] interface eth-trunk 1

    [*SwitchA-Eth-Trunk1] trunkport 10ge 1/0/1 to 1/0/2         //Add the two interfaces connected to the server to the Eth-Trunk.      
    [*SwitchA-Eth-Trunk1] port default vlan 2                                           
    [*SwitchA-Eth-Trunk1] commit                                                      

  2. Configure a network adapter group on the server.
    1. Choose Start > Control Panel > Network and Sharing Center. Click Change adapter settings. The Network Connections page is displayed.
    2. Right-click a network adapter to be added to the network adapter group, and click Properties. The Local Area Connection Properties window is displayed.
    3. Click the Network tab page and click Config under Connect using:. The Intel(R) Ethernet Server Adapter I340–T4 Properties window is displayed.
    4. Click the Teaming tab page, select Teaming with other adapters, and click New Team. The New Team Wizard page is displayed. Create a network adapter group on the page.
    5. (Optional) Name the new group, for example, WF, and click Next.
    6. In the Select the adapters to include in this team area, select network adapters to be added to the network adapter group, and click Next.
    7. In the Select a team mode: area, select IEEE 802.3ad Dynamic Link Aggregation, and click Next.

      NOTE:
      The network adapter group type is generally IEEE 802.3ad dynamic link aggregation in load balancing mode. Configuration notes for this type of network adapter group are as follows:
      • The switch is required to support the 802.3ad standard and the Eth-Trunk on the switch be configured to work in static LACP mode before the network adapter group is created.
      • Each group supports two to eight adapter interfaces.
      • All member network adapters in the network adapter group must connect to Ethernet interfaces working at the same rate on the switch.
      • All member network adapters must work in full-duplex mode.
      • The network adapter group must connect to a CE series switch or a stack system, and member network adapters connected to the same switch must work at the same rate.

      Before changing the network adapter group type from IEEE 802.3ad to AFT, delete the Eth-Trunk configuration on the CE switch, release the physical interfaces, and assign VLANs to the interfaces. Otherwise, the CE switch cannot ping the server. If the network adapter group type is changed to AFT, the server does not exchange LACPDUs with the switch. As a result, the aggregated link configured on the switch goes Down, and the switch cannot ping the server.

    8. Click Done and wait for the network adapter group configuration to be complete.
    9. Choose Start > Control Panel > Network and Sharing Center. Click Change adapter settings. The Network Connections page is displayed. Right-click the created network adapter group, and click Properties.
    10. Click the Network tab page and double-click Internet Protocol Version 4 (TCP/IPv4) to configure the IP address of the network adapter group.
    11. In the Internet Protocol Version 4 (TCP/IPv4) Properties window, select an IP address obtaining mode, and click OK.

Checking the Configuration

  1. Run the display eth-trunk [ trunk-id ] command in any view to check the Eth-Trunk status. Check whether the Eth-Trunk status is normal based on key information in Table 3-6.
    <HUAWEI> display eth-trunk 1
    Eth-Trunk1's state information is:
